THE PROBLEM

Memory chips are stalled in their quest to continue Moore’s Law, limited to 22 nanometers, which indicates that equivalent physical oxide thickness will not scale below 0.5 nm (about twice the diameter of a silicon atom), which is the expected value at the 22 nm node. According to Wikipedia, this is an indication that CMOS scaling in this area has reached a wall at this point, possibly disturbing Moore's law. On the ITRS roadmap, the successor to 22 nm technology will be 14 nm technology.

THE SOLUTION

Quantum dots are conceived as a possible new advanced material for this purpose due to their small 2nm to 10nm size and semiconductor characteristics. Other materials are being explored but quantum dot advantages in uniformity, custom characteristics, flexibility to use different metals to make optimal QD, and reliable production and cost make Quantum Materials Tetrapod and QDX™ Quantum Dots excellent choices.
